Propagate group edits to ENA projects

[corneliusroemer]

Now we can edit group info, however, with current code in ena-submission, changed group info won't propagate to already existing projects.

At some point, we'll want to make it possible to update projects once the group is updated.

Currently, group info is requested from backend only once when the project gets created:

loculus/ena-submission/scripts/create_project.py

Line 248 in a70c205

group_info = get_group_info(config, row["group_id"])[0]["group"]
